LOCK.

Application filed September 23, 1922. Serial No. 590,139.

T0 all whom t may concern:

Be it known that I, ANDREW SALATA, a citizen of the United States, and aresident of the city of New York, borough of Manhattan, in the countyand State of New York. have invented a new and improved Lock, of whichthe following is a full, clear, and exact description.

This invention relates to a lock, and has for an object the provision ofa simplified and improved construction of lock of the general ty e setforth in my copending application, g 1922, entitled Lock Another` objectresides in the provision of means whereby a simple, efficient lock isproduced involving the necessityfor a min` imum number of parts,enhancing the econ` omy of manufacture.

A further object resides in such simplification of the operation of thedevice that y the liability of the parts to get out of order is stillfurther reduced.

A still further object resides in the particular construction andarrangement of parts which are hereinafter described and claimed andshown in the accompanying drawings.

The invention is illustrated in the drawings, of which- Figure 1 is avertical section taken on the line l-l of Fig. 3.. l

Fig. 2 is a section taken on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal section taken on the line 3 3 of Fig. l.

The form of the invention shown in the drawings is a preferred form,although it is understood that modifications in the con-` struction andarrangement of the parts and in the character of the materials used maybe adopted without departing from the spirit of the invention,

The invention contemplates the inclusion of certain elements within alock casing when suitably fastened within a recess in a door or similarmember. This casing contains a slidable bolt 2 adapted to be movedbackward and forward, s0 that its end when it is moved forward willproject into a keeper casing 3. The end of the bolt has a dependentportion 4 to be engaged by a flange 5 mounted on the upper edge of aspring-pressed latch member 6 held upward by a spring 7 and disposedwithin the keeper casing 3. As long as the flange 5 erial No. 541,987,filed March 8,

projects upwardly back of the depending portion or finger 4 of the bolt2 the bolt cannot be withdrawn from the keeper casing 3. This bolt ismounted within the casing 1 by being provided with a slot 3 throughwhich a flange 9 formed on the casing projects and supports `said boltfor sliding movement.

The rear end of the bolt 2 is provided with an enlarged head 10. Thishead is adapted to be engaged by one part of a lever 11 pivoted at 12and having an enlarged laterally extending head portion, such as 13,shown particularly in Figs. 2 and 3, which is adapted to be engaged by akey-operated member 14. This key-operated member is connected to a lockbarrel 15 which is in any well known'manner operated by a key` from oneside of the door 16.

Whenever the key-operated member 14 engages the head 13 of lever 11,this lever is retracted againstthe action of the spring 17 disposedwithin the casing 1 and engages the head 10 at the rear end of the bolt2, tending to retract the bolt into the casing 1. However, before thebolt can b e retracted the latch member 6 must be disposedto disengagethe flange 5 from the nger 4.v This disengagement is effected by thedepression of the end 18 of an arm orlever 19 pivoted at 2O in a slot2,1, seen particularly in Fig, 2, formed in the bolt V2. The other endof this lever 19 is provided with a `curved por tion 22 which is adaptedtofbeengaged by a lug or shoulder 23 von a portion of the lever 1l lyingadjacent thereto. This engagement will elevate the rear end of the lever19 but will depress the forward end, causing the disengagement of theflange 5 as above mentioned. This operation of the lever 19 is effectedjust before the lever 1l engages the head 10, so that the bolt 2 may beproperly retracted. The retraction of the bolt 2 is opposed by a spring24 also disposed within the casing l.

The lever 11 is also adapted to be operated by the movement of a knobshaft 25 which is provided with a plate 26 attached thereto havingextending portions 27 and 28 on either side of the shaft so that eitherone of these extensions is adapted to engage the lever 11 in whateverdirection the knob shaft 25 is moved to move the lever 11 and retractthe bolt 2 in the usuallmanner. It may be desirable to lock the knobshaft 25, and to this end I provide a slot or recess 29 in the plate CLIand

26. ln this recess the end of a bar 3() is adapted to lie. This bar canbe actuated by the depression of a button 3l disposed able bolt toretract the same, this pivoted bolt, however, being held in its forwardposition by a latch member which can only 'be disengaged by theactuation of a pivoted bar or lever the actuation of which is effectedby the first mentioned lever just before `it.

engages the bolt to retract it.

What I claim is:

l. A lock including a slidable bolt having a dependent finger portion onits end, a

latch member engaging said finger portionV to hold the boltin itsforward position, a pivoted lever, key-operated means for moving saidlever, and means on the bolt to be engaged by said lever to retract saidbolt.

2. A lock including a slidable bolt having a dependent finger portion onits end, a latch member engaging said finger portion to hold the bolt inits forward position, a pivoted lever, key-operated means for movingsaid lever, means on the bolt to be engaged by said lever to retractsaid bolt, and a second pivoted lever engaged by the first pivotedlever, said second pivoted lever adapted to disengage the latch memberfrom the end ofthe bolt just before the first pivoted lever engages thebolt to retract the same.

3. A lock device which includes a casing, a slidable bolt therein, adependent finger on the end of the bolt, a latch member adapted toengage the finger to hold the bolt in a definite position, said bolthaving a recess or slot in its lower face, anda pivoted disengaginglever in said recess adapted to engage the latch member to remove itfrom engagement with the dependent finger.

4L. A locking device which includes a slidable bolt having a head at oneend, a pivoted operating lever adapted to engage said head, a pivotedlatch disengaging lever mounted on said bolt, a key-operated member, andprojections on said first mentioned pivoted lever adapted to engage thelatch disengaging lever and the key-operated member.

5. A lock device which includes a slidable bolt adapted to project intoa keeper casing, a latching member in said keeper casing to engage theend of the bolt and hold it in its forward position, a pivoted latchdisengaging member mounted on said bolt and adapted to be moved todisengage the latch member from the end of the bolt, a head on saidbolt, an operating lever Within the lock casing, and a projection onsaid operating lever to engage the latch disengaging member prior to theengagement of said lever with the head on the bolt.

6. A lock device which includes a slidable bolt adapted to project intoa keeper casing, a latching member in said keeper casing to engage theend of the bolt and holdit in its forward position, a pivoted latchdisengaging member mounted on said bolt and adapted to be moved todisengage the latch member from the end of the bolt, a head on saidbolt, an operating lever within the lock casing, a projection on saidoperating lever to enagage the latch disengaging member prior to theengagement of said lever with the head on the bolt, and keyperated meansto engage the operating leveli').
